Make 8 very thin patties. Place about 2 tbs of blue cheese on top of 4 of the patties. Place the remaining thin patties on top of the ones containing the cheese; seal well.
Broil or grill about 5 minutes each side for medium doneness or until patty is 160 degrees F internal temperature. FYI 160 degrees is recommended by the USDA to kill bacteria that may be in ground meat.
